Anyone have a HSG test

My doc is scheduling an HSG test for me after I go in for an ultra sound...I'm happy that the processes is finally moving to figure out what's going on but my anxiety is out of control i have always wondered if I have endometriosis...
I'm so nervous to have this done not bc of the pain but for the answer I might receive I don't think i can handle anymore bad news by husbands results didn't come back with all + so this would be a double blow... 
Has anyone taken this test? How long till u get the results back?
